The group - consisting of Ronan Keating, Keith Duffy, Mikey Graham and Shane Lynch - performed at Ronan's Emerald and Ivy Ball in Battersea, south London, on Saturday night (21.11.09) where Stephen's grieving husband took to the stage to pay tribute to the late pop star.

Ronan told him: "With you being here tonight, the four of us, Boyzone, feel like five."
